Interface XMLEventAllocator

public interface XMLEventAllocator

This interface defines a class that allows a user to register
a way to allocate events given an XMLStreamReader. An implementation
is not required to use the XMLEventFactory implementation but this
is recommended. The XMLEventAllocator can be set on an XMLInputFactory
using the property "javax.xml.stream.allocator"

allocate

This method allocates an event given the current
state of the XMLStreamReader. If this XMLEventAllocator
does not have a one-to-one mapping between reader states
and events this method will return null. This method
must not modify the state of the XMLStreamReader.

allocate

This method allocates an event or set of events
given the current
state of the XMLStreamReader and adds the event
or set of events to the
consumer that was passed in. This method can be used
to expand or contract reader states into event states.
This method may modify the state of the XMLStreamReader.
